Electrochemical Potential Controlling Flotation

Clearly, if there is a difference in the potential at which different minerals float with a particular collector, then control of the potential should allow flotation separation. For example, Chander and Fuerstenau 1983 showed that chalcocite could be separated from molybdenite through appropriate choice of the potential of flotation.
